“…Nomiamastrel virus is one of the few mastreviruses/mastrevirus-like sequences to be identified in the Americas. The others include the dragonfly-associated mastrevirus [ 7 ], maize striate mosaic virus [ 77 , 78 ], sugarcane striate virus [ 79 ], switchgrass mosaic-associated virus 1 [ 80 ], and sweet potato symptomless virus 1 [ 57 , 58 , 81 ]. Although the vector of this virus remains unknown, it can be hypothesized that given the phylogenetic relationship of the CP amino acid sequence to that of other mastreviruses, it is likely vectored by a leafhopper.…”

Members of the Geminviridae family are circular single-stranded DNA plant-infecting viruses, some of which impact global food production. Geminiviruses are vectored by sap-feeding insects such as leafhoppers, treehoppers, aphids, and whiteflies. Additionally, geminivirus sequences have also been identified in other insects such as dragonflies, mosquitoes, and stingless bees. As part of a viral metagenomics study on honeybees and solitary bees (Nomia sp.), two geminivirus genomes were identified. These represent a novel citlodavirus (from honeybees collected from Westmoreland, Jamaica) and a mastrevirus-like genome (from a solitary bee collected from Tempe, Arizona, USA). The novel honeybee-derived citlodavirus genome shares ~61 to 69% genome-wide nucleotide pairwise identity with other citlodavirus genome sequences and is most closely related to the passion fruit chlorotic mottle virus identified in Brazil. Whereas the novel solitary bee-derived mastrevirus-like genome shares ~55 to 61% genome-wide nucleotide identity with other mastreviruses and is most closely related to tobacco yellow dwarf virus identified in Australia, based on pairwise identity scores of the full genome, replication-associated protein, and capsid protein sequences. Previously, two geminiviruses in the Begomovirus genus were identified in samples of stingless bee (Trigona spp.) samples. Here, we identify viruses that represent two new species of geminiviruses from a honeybee and a solitary bee, which continues to demonstrate that plant pollinators can be utilized for the identification of plant-infecting DNA viruses in ecosystems.

“…Jones & Medina (2020) califican a D. maidis como un "super vector" por ser un eficiente trasmisor de patógenos que afectan al maíz. Estos son: dos Mollicutes [el "espiroplasma del maíz o corn stunt spiroplasm (CSS, Spiroplasma kunkelii)", y el "Maize Bushy Stunt Phytoplasms" (MBSP, Candidatus Phytoplasma asteris)], y dos virus [el "Maize Rayado Fino Virus" (MRFV) y el "Maize striate mosaic Virus" (MSMV)] (Oliveira et al 1998;Giménez Pecci et al, 2002Vilanova et al, 2022;Ruiz Posse et al, 2023). Estos patógenos, solos o combinados, producen la sintomatología y enfermedad compleja denominada "achaparramiento o raquistismo del maíz".…”

Due to its frequency, abundance in crops, and remarkable capacity to efficiently transmit at least four pathogens, Dalbulus maidis stands out as one of the most significant threats to maize crops in Latin America. The recent population outbreak of this pests observed in Argentina has highlighted its potential to cause significant damage to maize crops, with estimated losses reaching up to 80%. Consequently, one of the most pressing needs is to integrate and disseminate fundamental knowledge on various bioecological aspects of this vector to researchers, technicians and stakeholders interested in maize crop health. This contribution is a summary of the knowledge on the main biological characteristics of the vector acquired over more than 50 years. Among other topics, the provided information encompasses its identification, biological traits, distribution, pest significance, life cycle and development, voltinism, host plants, behaviors, and natural enemies. All this information is crucial for developing an effective pest management program in Argentina.
